17 Claims.

This invention relates to an apparatus for charging and rechargingsiphon bottles with carbonatedwater and free gas.

Carbonated water is usually dispensed and sold in so-called siphonbottles and such bottles have usually been filled or charged in plantswhere expensive equipment is provided. The cost of collecting anddistributing such bottles has therefore been an important factor.Usually neighborhood stores such as drug stores have carbonatingequipment, that is, equipment for making carbonated water and couldtherefore refill or recharge such siphon bottles at a very small cost ifthey had available a suitable inexpensive filling device thereby greatlyreducing the cost of such siphon bottles to the consumer.

It is therefore an object of this invention to provide a suitablefilling device for charging and recharging such siphon bottles whichoccupies a very little space and which is well adapted for the purposeintended.

As the amount of carbon dioxide gas which water will absorb and retainis almost directly proportional to the temperature of the water, aconsiderable amount of gas frees itself from the water and accumulatesin the upper part of the siphon bottle when the temperature of the wateris elevated to any great extent. In charging or refilling siphon bottleswith carbonated water it is customary to fill the bottle only aboutthreefourths full. The invention herein described contemplates firstcharging the siphon bottle with a predetermined quantity of carbonatedwater and then charging the bottle with an additional amount of freegas. The carbonated water with which the bottle is first charged hasabsorbed therein a substantial amount of gas but if the bottle and itscontents are substantially cooled, the water will tend to absorb anadditional amount of free gas due to the fact that the temperature ofthe water has been decreased and also due to the fact that the free gasin the upper portion of the siphon bottle is at a pressure of the orderof 125 pounds per square inch. This free gas being under considerablepressure also aids in dispensing the carbonated water from the bottle atconsiderable pressure until all of the water has'been dispensed from thebottle.

Specifically the invention comprises an apparatus for first charging orrecharging the bottle with carbonated water and then charging the bottlewith an additional quantity of free gas at considerable pressure. Theapparatus consists essentially of a dispensing head which includes-apair of discharge outlets through which carbonated water and gas may bedischarged. It is customary to charge siphon bottles through thedischarge spout'thereof. The apparatus herein disclosed has twodispensing outlets which are disposed closely adjacent each other andare shaped to receive therein the delivery end of the discharge nozzleof the dispensing bottle. A single lever is also provided forpositioning and holding the siphon bottle first in the position to becharged with carbonated water and then in a position to be charged withfree gas. Carried' by the lever is a device for opening the siphonbottle dispensing valve so as to permit the bottle to be charged throughthe discharge spout thereof.

.16 The d1spens1ng head'is provided with a pair of valves forcontrolling'the delivery of carbonated water and free gas. These valvesare positioned so as to be actuated by the dispensing nozzle of thesiphon bottle to open the same. The entire filling device is simple andcompact in construction and comprises very few parts which are welladapted for production at comparatively low cost.

Further and more limited objects of the invention will appear as thedescription proceeds" and by reference to the accompanying drawing in.which Fig. 1 is a perspective view showing our improved apparatusattached to a counter or bar;

Fig. 2 is a vertical sectional View on the line 2-2 of Fig. 1; and Fig.3 is a view in side eleva- .tion showing a siphon bottle in the positionin which it will appear when being charged.

Referring now to the drawing, the charging apparatus consistsessentially, of a supporting member I which is adapted to have one endse-' cured to the under side of a counter or bar 2, the opposite endbeing disposed at an angle and having an enlarged head portion which isshaped in section, as shown most clearly in Fig. 2. The

supportingmember I is preferably in the form 0 a die casting and hasformed thereon a strengthening rib 3. Secured to thesupporting member Iand extending upwardly therefrom is a post 4 which is interiorlythreaded and is secured in place by means of a screw or bolt 5.Adjustably" secured to the post 4 and extending outwardly therefrom isan arm 6 which is held in the adjusted position by a set screw 1.Pivotally secured to the outer end of the arm 6 is an arm 8,

which is also preferably formed of a die casting, and has formed thereona head member 9 hav-- ing therein a pair of sockets or openings lfl'andI I each of which receives therein a rubber capor sleeve IZ. Pivotallysecured to thearm 8 is-a lever l3 which also is preferably formed of adie casting and provided with a pair of outwardly projecting arms I4 andI5 between which a roller I6 is rotatably mounted.

The dispensing head has formed therein a pair of bores or passageways I!and i8 which receive therein a pair of washers l9 and 2!]. Fittingwithin the bores l1 and 18 respectively, are a pair of guide members 2|and 22 which have formed thereon valve seats 23 and 24 against whichseat the valves 25 and 26. Loosely fitting within the guide members 2!and 22 are a pair of valve actuating members 2'! and 28 which are shapedin section, as shown most clearly in Fig.

2 and provided with communicating ports and bores to permit flowtherethrough when the valves are opened. Fitting over the guide members2| and 22 are a pair of flexible gaskets 29 and 30. The referencecharacters 3| and 32 designate a pair of nipples or collars whichthreadedly engage the dispensing head and hold the valves and associatedparts in place, the nipples 3| and 32 each having an opening therein ofsuch size as to receive therein the discharge end of the dispensingnozzle of a siphon bottle. Secured in the lower ends of the dispensinghead are a pair of nipples 33 and 34. Connected with the nipple 33 is asupply line 35 which connects with a suitable source of carbonatedwater. Connected with the nipple 34 is a supply line 36 which isconnected with a source of supply of carbon dioxide gas.

The reference character 37 designates a siphon bottle of the usualconstruction which has applied thereto a closure member 38 which hasformed integral therewith a dispensing spout 39. The sockets or openingsIll and H are designed to fit over the end of the closure member of thesiphon bottle. When it is desired to charge or re-charge a siphonbottle, the end of the dispensing nozzle of the bottle is first placedwithin the fitting 3| in the position shown in Fig. 3. The arm 8 is thenmoved to engage the head member 9 with the upper end of the closure forthe siphon bottle. In this position of the bottle the lever l3 willassume the position shown in Fig. 3 with the roller l6 disposed abovethe lever 40 which serves to open the siphon bottle dispensing valve. Tocharge the bottle with carbonated water it is merely necessary to firstsqueeze the lever 13 to move the lever 40 downwardly to open the siphonbottle dispensing valve and to simultaneously depress the arm 8 whichforces the delivery end of the dispensing nozzle of the siphon bottleinto engagement with the valve actuating member 2'! to move the valve 25away from its seat against the tension of a coil spring 42 whichnormally urges the water valve to closed position. When the valve 25 isopened, the carbonated water being under pressure, will flow through thepipe 35 and thence through the siphon bottle dispensing nozzle to theinterior of the bottle, the dispensing valve being open. It is customaryto fill the dispensing bottle about three-fourths full. When this amountof carbonated water has been delivered to the siphon bottle, the leverI3 is released and the arm 8 is then lifted upwardly. The dispensingvalve being urged to its seat by a spring (not shown) is moved to closedposition. The dispensing nozzle of the siphon bottle is then placedwithin the nipple 32. The arm 8 is first depressed, and the lever i 3then moved to open the siphon bottle dispensing valve. In this positionof the parts free gas under pressure will flow through the pipe 36 andthrough the siphon bottle dispensing nozzle. This carbon dioxide gas isunder a pressure or about pounds per square inch. The gas will flow intothe bottle until the remaining space in the bottle is filled with gas ata pressure of the order of 125 pounds per square inch. Siphon bottlesare usually constructed to withstand a pressure of 250 pounds per squareinch, although it is contemplated that the siphon bottle be enclosedwithin a suitable cage or casing to prevent injury to the operatorshould the siphon bottle burst as a result of the high pressure. Torelease the siphon bottle, it is merely necessary to release the leverl3 and swing the arm 8 to the position shown in Fig. 1.

After these operations, the siphon bottle is about three-fourths full ofcarbonated water and the remaining space in the bottle is filled withcarbon dioxide gas at a pressure of approximately 125 pounds per squareinch. As the siphon bottle contains a considerable quantity of free gasunder a substantial pressure, the water in the bottle will tend toabsorb an additional amount of gas when it is cooled to any substantialdegree. This excess quantity of free gas also aids in dispensing thecarbonated water from the siphon bottle at considerable pressure untilall of the water is dispensed.

It will now be clear that we have provided an apparatus for chargingsiphon bottles which will accomplish the objects of the inventionhereinbefore stated. It is of course to be understood that variouschanges may be made in the details of construction and arrangement ofparts without departing from the spirit of the invention as theembodiment of the invention herein disclosed is to be considered merelyas illustrative and not in a limiting sense and that the invention islimited only in accordance with the scope of the appended claims.
